Question

a car jack with a mechanical advantage of 6 needs to produceand output force of 600 N to raise a car. what inout force is required

Answer 1

Answer:

$\large \boxed{\text{100 N}}$

Explanation:

The mechanical advantage (MA) is the ratio of the output force  to the applied force.

$\begin{array}{rcl}MA &=& \dfrac{F_{\text{o}}}{F_{\text{a}}}\\\\6 &=& \dfrac{\text{600 N}}{F_{\text{a}}}\\\\6F_{\text{a}} & = &\text{600 N}\\\end{array}$

$\begin{array}{rcl}F_{\text{a}} & = & \dfrac{\text{600 N}}{6}\\\\& = & \textbf{100 N}\\\end{array}$

The input force required is 100 N.
